Definitions

  • the present invention refers to a digging apparatus applicable to a bucket loader, e.g. a tractor loader and of the type used for smaller digging work, such as trenching and e.g. in agriculture, park management or the like.
  • Such an apparatus must be so easy to mount on the loader that mounting and dismounting can be accomplished in short time and by a single machine operator.
  • the apparatus should furthermore be light and flexible at the same time as it has great working range and mobility. It is of course also desirable that the apparatus is inexpensive and wear resistant.
  • Older apparatuses of this kind have commonly fulfilled only one or some of these requirements, whereas all requirements have to be fulfilled for making an apparatus, which is useful under intended conditions, which does not occupy the loader for unnecessary long time, and which is simultaneously flexible, robust and inexpensive.
  • US-A-3,802,586 presents an apparatus of this type, which incorporates a connecting device intended to be attached to said bucket loader and having a pivot axle connected thereto, the pivot axle lying in a vertical plane and extending mainly perpendicularly to the extension of a digging beam, which is pivotably supported about the pivot axle, a bucket attached to the free end of the beam, which bucket is operable by means of a driving device, and at least one hydraulic actuator adapted to bring about the swinging of the digging beam about the pivot axle and arranged to transfer pivot force to the digging beam at a short distance from the pivot axle, and this apparatus has fulfilled several of the above requirements.
  • a drawback of this known device is that it has a very rigid and unflexible digging beam and it is therefore commonly possible to apply it to one type of loader only, at the same time as the digging beam in practice lacks ability of adaption to different digging conditions and positions.
  • the purpose of the invention is now to provide a digging apparatus having high flexibility and therefore being applicable to different loaders and which fulfills the requirements above defined and this has been achieved thereby that the apparatus has been given the features appearing in the accompanying claim 1.
  • FIG 1 is schematically shown a tractor loader 1 with a loader arm 2, which at its outer end is provided with connecting members 3 for interconnection with quick coupling brackets 4 attached to one end of a digging apparatus 5 according to the invention.
  • the tractor loader can be substituted for every other suitable bucket loader provided with a corresponding, arbitrarily positioned loader arm.
  • the digging apparatus 5 is thus connected to the bucket loader in question via an easily operable quick coupling of known type, which has however been supplemented with stabilizing shoulders, shown at 6 in figure 2, and with other reinforcing means of proper type.
  • an easily operable quick coupling of known type, which has however been supplemented with stabilizing shoulders, shown at 6 in figure 2, and with other reinforcing means of proper type.
  • the digging apparatus 5 itself incorporates a plate 7 fitted to the quick coupling brackets and provided with brackets, which support a vertical pivot axle 8.
  • a bracket 9 On this vertical pivot axle 8 is pivotably supported a bracket 9, which in turn supports a digging beam 11 articulated on a first horizontal axle 10, and a stay 13 which is articulated about a second horizontal axle 12 situated at a higher level, the opposite end of said stay being pivotably connected to an attachment 14, arranged on the digging beam at a distance from the digging beam support 10.
  • this attachment 14 there is also fitted one end of a hydraulic piston and cylinder device 15, adapted with its other end to act upon a link 16, which transfers movement to a bucket 17 pivotably supported at the outer end of the digging beam. Transfer of the movement to the bucket is not critical for the invention but different conventional methods can be utilized.
  • Figure 3 shows in more detail how the digging beam 11 as well as the stay 13 are both telescopically adjustable and both units may consist of square tubes or round hollow profiles, which are preferably equipped with cooperating guiding members, e.g. guiding shoulders arranged in one of the tubes and engaging the other tube, or by means of profiles with forks or the like, welded thereto.
  • cooperating guiding members e.g. guiding shoulders arranged in one of the tubes and engaging the other tube, or by means of profiles with forks or the like, welded thereto.
  • FIGS 4 and 5 are shown in schematic side and top views in larger scale, digging apparatus components such as connecting members, pivot axles, the upper part of the digging beam and the stay, and the figure intimates a preferred solution of the adjustability of the digging beam and the stay respectively, whereby the two portions of the digging beam 11a, 11b and of the stay 13a, 13b respectively project into each other telescopically and are lockable in carefully defined mutual positions, by means of bolts 18.
  • This shown solution is however only one of several possible embodiments, whereby it is possible instead .to have a stepless adjustability by providing the two telescopingly cooperating profiles with cooperating threads, or with external adjustment members of different types.
  • axle journal 19 is intended to cooperate with a hydraulic actuator in the form of a piston and cylinder device 20, which at its opposite end is attached to a horizontal profile 21 situated above the plate 7, which profile projects perpendicularly from the digging beam.
  • a hydraulic actuator 20 thus can be located in such a manner that its power acts upon the bracket 9 in a point 19 situated very near its pivot axle 8, it is possible to achieve a very big pivot movement. Due to the fact that the pivot axle 8 furthermore is situated at a distance from the plate 7 and the hydraulic actuator 20 is situated above the pivot axle 8 but below the upper profile 21, this big pivot movement will not be hampered by these components.
  • the shown solution of the driving of the digging beam pivoting about the vertical pivot axle 8 is likewise only one of several possible embodiments, whereby the essential is that the point of attack of the hydraulic actuator is near to the vertical. pivot axle of the digging beam. It is thus within the scope of the invention possible to provide the profile 21 with a bracket, which projects in the digging beam direction, whereby the hydraulic actuator is attached to this bracket. It is hereby possible to obtain that the hydraulic actuator is mainly perpendicular to the digging beam in the "zero" position of the digging beam.
  • Figure 6 shows in a perspective view from one side how the digging apparatus can be provided with supporting legs 22, which either can be detachable and easy to mount when the digging apparatus shall be detached from the loader on which it is attached or which supporting legs may be pivotably fitted to the structure on or adjacent the plate, thus that they can be folded up and locked along the digging beam when the apparatus is attached to a supporting machine.
  • the digging apparatus forms a device which fulfills the initially mentioned requirements in a simple and efficient manner.
  • the stay 13 stabilizes the digging beam 11, which thereby can be of rather weak dimensions, at the same time as the stay allows adjustment of the working range of the apparatus, due to its adjustability.
  • the location of the hydraulic actuator far back entails that the power exerted by the hydraulic actuator can be utilized very efficiently.
